atherogenesis, and subsequent toxicity, to prevent angiogenesis evoked by low oxidized LDL concentration (monitored by the formation of capillary tubes on Matrigel) and to inhibit intracellular ROS increase involved in the angiogenic signaling. A structure/activity study has been carried out and finally allowed to select the phenolic diaryl ether hydralazine derivative 2a, sharing all these protective properties
衍生自二芳基和二芳基醚羟基苯甲醛框架1和2的一系列双hydr已被合成为潜在的抗氧化剂和抗血管生成剂,这是限制动脉粥样硬化和心血管事件所需的两个特性。对这些化合物的中和自由基形成,阻断内皮细胞诱导的低密度脂蛋白氧化(通过TBARS的形成进行监测),动脉粥样硬化形成的必要步骤以及随后的毒性(防止低氧化引起的血管生成)的能力进行了评估。 LDL浓度(通过在Matrigel上形成毛细管来监控)并抑制涉及血管生成信号的细胞内ROS的增加。进行了结构/活性研究,并最终选择了酚二芳基肼苯并肼衍生物2a共享所有这些保护特性,这对进一步开发很有希望。
